CANE-cRusl-IER.

SPECIFICATION forming part of Letters Patent No. 615,590, dated December6, 1898.

Application ned March 7,1898. semina. 672,917. (Nomade To tl whom it mayconcern:

Be it known that I, BUEoHAED THoENs, a subject of the Emperor ofGermany, residing at New Orleans, in the parish of Orleans and State ofLouisiana, have invented certain new and useful Improvements inCane-Crushers; and l do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to improvements in cane-Crushers intended to giveto the cane a preliminary maceration or crushing before it is fed to themill proper. It has been found that this preliminary maceration orcrushing of the cane before it is fed to the mill proper not onlyincreases the capacity of the mill` to handle large quantities of cane,but also increases the actual extraction of juice from the cane.

My invention is especially intended to provide means whereby thewell-known tworoller mills, fast becoming obsolete, may be convertedinto crushers for the preliminary crushing of the cane, as has alreadybeen described.

Reference is had to the accompanying draw. ings, in which the same partsare indicated by the same letters in both views.

Figure l represents a perspective view of an improved cane-crusherconstructed according to my invention. Fig. 2 represents an end view ofthe two rollers as detached from the housing and shows the relativepositions of the longitudinal grooves in the shell of the rollers. Y

A represents the housing made of any snitable or well-known type, inwhich the rollers are journaled and beneath which the upper roller issecured in place by means ofthe bearing-block C, the cap B, and thebolts D.

The two rollers- E and E are mounted on shafts F and F', suitablyjournaled in the housing A, and these shafts are provided withgear-wheels G and G', which are of equal size, and thus cause the tworollers to revolve at The two rollers may be driven in any convenientway-as, for instance, by cog-gearing not shown) connecting the shaftslF' with the main engine (not shown) of the mill. These gearwheels are soarranged relative to the longitudinal grooves e' in the shell e of therollers E and E that the'grooves of one roller will always come inbetween the corresponding grooves on the opposite roller, as shown inFig. 2. These grooves are preferably made in the form of arcs of smallcircles which indent the cylindrical surface of the crushing-roller.Thus the edges of these grooves e will bite into the cane and feed thesame in between the two crushing-iollers, at the same time in aceratin gthe cane somewhat, while the cylindrical portions of the rollershell ebetween these grooves e' will subject the cane to a preliminary crushingand will extract part of the juice therefrom. These elemental orlongitudinal grooves c' may be cut. in the shells of the rollers of anytwo-roller mill, or two of the rollers of a discarded threeroller millmay be used for this purpose, and in this way an old and inefficientmill may be converted into a new and ecient Crusher.

The various advantages of the herein-described construction not fullydwelt upon herein will be understood by any one skilled in the art.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent of the United States. is

1. A cane-Crusher consisting essentially of two rollers, each providedwith a plurality of equidistant longitudinal grooves, with means forrotating the two rollers at the same speed, and for maintaining thealternation of the grooves on the one roller between the grooves on thenext opposite roller as the two rollers revolve, substantially asdescribed.

2. lu a cane-Crusher, the combination with two rollers provided witheqnidistant longitudinal grooves thereon, the grooves of one rollerbeing opposed to the cylindrical portion of the opposite roller, withgearing for driving the two rollers at the same rate of speed wherebythe relative positions of the grooves and cylindrical portions on theoppo site rollers will remain the same, substantially as described. v

In testimony whereof I aihx my signature in presence of two witnesses.
